Hi Rador! Dr. Schulze doesn't AGREE with that Information about Chaparral, but I don't know of ANY Web-Pages, that has his Comments on Chaparral. He does use Chaparral Herb and Resin in his Blood and Lymph Cleansing Formula known as DETOXIFICATION FORMULA!
Here is a Web-Page, that I just found about the MISINFORMATION/DISINFORMATION on Chaparral and Comfrey, that have either been BANNED or STRONGLY WARNED AGAINST to use by the F.D.A.
